For more detail information refer to the article "Desalination of seawater by successive heating of thin layers of water using solar radiations from a Fresnel concentrator"[1], the preprint "Detail Design - Linear Fresnel concentrator Steam Generator"[2] , the preprint Steam Flow formulation of the Linear Fresnel concentrator Steam Generator[3] and the preprint ‘Solar Heat Transfer formulation for the Steam generation from seawater based on Linear Fresnel Concentrator’[4].The first process is the condensation process which reuse an existing process. We recommend to use the HeatSink technology combined to cooling plate. For more information about this condensation process we can refer to this article ‘Improvement of condensation step of water vapor in solar desalination of seawater and the development of three-ply membrane system’[5]. The second process, which the innovation aspect for this paper, is to generate hydro-electrical energy from the condensate water in the first process.

The purpose of this paper is to formulate the heat transfer needed to generate continuously the steam from the “Linear Fresnel concentrator Steam Generator” according to its dimensions. For more detail information refer to the article "Desalination of seawater by successive heating of thin layers of water using solar radiations from a Fresnel concentrator"[1], the preprint "Detail Design - Linear Fresnel concentrator Steam Generator"[2] and the preprint Steam Flow formulation of the Linear Fresnel concentrator Steam Generator[3]. The heat transfer flow assessment depending of many dimensions is the key point out put of this paper. At the glance, these dimensions are the geometry of the Linear Fresnel Concentrator, the tilt to the sun's rays, the length , the radius of the tangled cylinders, the thickness of the annulus spaces and the cavity between the composed device absorber and mirror. The device absorber is composed of the tangled cylinders and the steam collector. Note that the known LFR applications for both industrial and power sectors requires medium temperatures ranging from 100°C to 250°C. The flat plate solar collectors are suitable for low temperature applications maximum up to 80°C and parabolic concentrators are suitable for high temperatures applications above 300°C. Hence, the present work will focus on LFR with parabolic concentrator because sea water desalination requires reaching the boiling point under pressure near atmospheric pressure which is 100 °C. Furthermore, the diameter of absorber device for parabolic concentrator may vary from 5 in to 10 in which is much greater than tubes dimensions for trapezoidal cavity. Then, this dimension fact allows efficient flow water circulation and meaningful steam flow generation.[1] touzani, s. (2019, March 28).

Abstract: Vehicle is the important think to get the better live for peoples of sociaty. Currently the development of vehicles is increasing rapidly, especially vehicles that use friendly energy for enviroment such as electrical energy. The electric vehicles have been used for commercial cars as well as for competitions. The race vehicle is required to develop new technologies in the particular vehicle. The electrical Vehicle Researces has been carried out include the systems such as drive train, Cassis, frame, batree, system control etc, however in this paper will be discuss design of electric vehicles Frame for Competition. The proces design will be accordance with the rules competition, there is dimensions, weight, power of vehicle etc. the vehicle specification requarenment will be created concept design, then embodiment design and detail design, theres will be figure out the strength and ergonomics frames to satisfy the safety criteria. Results of design obtained dimensions of frame 1800x800x1000 mm, 35.7 kg of weight, and material frame JIS G 3445 STKM 11 is obtained for static load load while stress of maximum impact load is 91.6 Mpa, deflection 0.61 mm and safety factor 2, 1.

Water in industry is used for operations such as production processing, washing, dissolving, cooling, transportation. Industries often require large amount of water with vary quality. Water quality depends on the purpose of water use. The steam electric power generation industry is defined as those establishments primarily engaged in the steam generation of electrical energy for distribution and sale. Those establishments produce electricity primary from a process utilizing fossil type fuel (coal, oil, or gas) or nuclear fuel in connection with a thermal cycle employing the steam –water system as the thermos-dynamic medium [9]. Water with in boiler drum and steam generation tubes and headers must be soft and clean. Reverse Osmosis is an effective and proven technology to produce water that is suitable for many industrial applications that require demineralized or deionized water with neutral pH and without turbidity and aggressive.

The seawater desalination technique presented in this article is based on a new technique for the production of water vapor which has the advantage of using solar energy with maximum evaporation efficiency. This innovation is limited to the production of steam and can be combined with a known technique of condensation of the steam in order to complete the desalination cycle of seawater. This technique is based on the simple principle that the heat transferred from the hot source to the cold source is maximum if the difference between their respective temperatures is kept at its maximum. Thus, by carrying out successive operations of heating thin layers of water, the technique makes it possible to maximize the efficiency of the evaporation by bringing the temperature of the fluid to its initial value at each iteration, thus enabling, according to the Newton's law, to favor the transfer of heat to water.Then, in this paper, we present the theoretical demonstration of the soundness of this technique by using the analogy with electricity using the equivalent resistance for circuits in parallel. Next, an application of the technique which is the subject of a patent of invention is presented in the detal. It is a desalination engine for seawater using solar radiation from a Fresnel concentrator. The presented invention makes it possible to produce steam continuously by heating thin layers of sea water by the Fresnel concentrator. The development prospects of the invention are also presented using the techniques of Nanotechnology.

In the last years, the European energy policy has required to increase the share of renewable energy sources in the national energy systems. It is important to diversify the energy system not to bring about a global crisis resulting from the fundamental lack of electricity. Unfortunately renewable sources are unstable and generate several problems during integration with the power grid. The solution is to store additional energy produced from renewable sources. In this way, energy can be used when there is a need. The paper discusses the study of the Power-to-Gas-to-Power installation using electrolysis and methanation processes at the energy storage stage and gas expanders during energy discharges. In addition, a part of the Heat Recovery Steam Generation installation has been implemented. The purpose of the work was to determine the impact of a given Heat Recovery Steam Generation installation on the efficiency of the entire installation and flue gas temperature at the outlet from Heat Recovery Steam Generator.
